Thanks everyone for the quick and in-depth replies. I guess since we are on a roll I will ask a few more here if you do not mind.
How can I control other characters, while they are already in my party? I have a feeling I should probably read more of the hints guide in game, but I am currently away from it. But I see no obvious way to make my warrior companion open a container of some sort. Only my main who is a Shaman can I physically control and then I have to collect anything useful and then drop it on the ground and then allow for an inventory check and mass pick up of my other character. It's a little awkward...
Also does simply carrying items on a person add weight to them at all? My warrior was picking up quite a bit and even picked up heavy armour, but was not emcumbered what so ever until he actually donned it. Do my characters carry magical bags of weightlessness regardless of size of items or is that a bug?
And finally for the time being at least, can we attack or kill innocent unimportant NPCs, regardless of the repercussions? Like a few prisoners on the first mission they were scattered and did not say much. I generally play a middle of the road or good hearted character my first play through, but I had saved and then tried to attack, but it said I could not talk to them while in the combat mode. Is there an over ride to still attack and kill what ever you want, or the game simply wont allow for it? Thank you.
